SPECIFIGATION fQrming part of Letters Patent No. 291,443, dated January 1, 1854.

Application filed October 15, 1883. (X model.)

To ctZZ whom-z t may concern.-

Be it known that I, HORACE Weeks, of Bos ton, in the county of Suffolk and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Nailing-llIachines, of which the following is-a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature, in which Figure 1 is a front view of a nailing-machine having my improvements. Fig. 2 is a view in perspective of two movable jaws containing the waste cutting, cut-off, andfeeding Fig. 3 is aview in elevation and plan of one'of the movable jaws, hereinafter more fully described. Fig. 4 is a view in plan 1 v and a vertical section on thewline :0 :10 of the other movable jaw, and Fig. 5 is a side ele- 2o vation of the machine.

The invention is an improvement upon that 1 described in my Letters Patent No. 280,267, dated June 26, 1883,and relates to the devices therein termed cuttingoff a-nc carrying 2 5 devicesthat is, mechanism for cutting away or severing a piece from the nail-wire to form the shank and barb of the nail, for severing the nail from the wire, and for feedingthe nail to the driver. In said patent I describe mecho anism for this purpose consisting of a movable and a fixed jaw, by which a nail-blank is first severed from the wire, and then its shank and barb formed.

In the present invention I use two movable 5 jaws instead of one movable and one station ary, and I cut the waste from the end of the wire to form the shank and barb of the nail before the nail is completed by being severed from the wire.

Referring to the drawings, A represents the movable jaw which cuts off or removes the waste, and B the movable jaw which severs the hail from the wire and feeds it into position under the driver 0. The movable jawA is provided with the cutting-edge a, which is like that described upon the movable jaw of said patent, with the exception that it is placed near one end of the jaw instead of centrally, as in the patent. This jaw is moved horizon- 950 tally by means of the cam-groove D in the cam-disk d on the main shaft of the machine,

and the lever d, whose fulcrum is at d, and lays hold of or is pivoted to the jaw (1 Upon the removal or cutting of the waste the jawA comes to rest, and the other jaw,.B, is then moved by means of the cam-groove D, lever (2, having its fulcrum at diand pivoted to the end of the jaw B at (1, cutting or severing the nail from the wire, as described in said patent, and feeding it into position beneath the driver 0. The wire is fed by any suitable feeding device, and I prefer that described in the Knowlton patents, No.225, 527 dated March 16, 1880, and N 0. 241,550, dated May 17, 1881, referred to in my said patent. 6 5

In Fig. l a portion of the wire-feeding mechanismnamely, the feed'rolls F F-is shown. These rolls are caused to move the wire to a stated distance equivalent to the length of the nail which it is intended to form, and by suitable means, described in said Knowlton patents, the extent of this feed maybe varied so that nails of any make may be formed. It enters between the jaws through the hole 6 in the jaw B, and is held by the recess '6' in said 7 5' jaw, and upon the movement of said jaw the nail-blank of course is severed therefrom, and the nail-blank is moved by it into position under the driver, as above explained. The edge of the hole 6 acts as a cutter in severing the nail-blank from the wire upon the move ment of the j aw B, and in this respectit acts like the cut-off described in the Knowlton patent of 1881. The jaw A has a vertical groove, (4', which, when it finally comes to rest after cutting the waste from the shank of the nail, comes in line with the driver 0. The inner surface of the movable j aw Ais cut out to form sufficient clearance for the escape of the waste of the nail, which is moved forward by the mond-shaped, if wire diamondshaped in crosssection is employed, or may be of any suitable cross-section to correspond to the cross-section of the wire.

Having thus fully described my invention, I

claim and desire to secure by Letters Patent whereby the waste is cut from the wire by 16 of the United States 1 the movement of one ja\v, and the nail then 1 The movable jaw A, provided with a outsevered from the wire and fed under the driver ting-edge cavity, a, and driving-recess a,with by the movement of the other jaw, all sub- 5 the movable jaw B, having the cutter e and stantially as and for the purposes described.
